Phate Posted September 12, 2016 Share Posted September 12, 2016 Wondering if this has happened to anyone else, this is only the second time it has happened to me. Head unit/climate control is a P204-UH from a 2007 LGT Limited. While I was driving in to work today, the screens for both the radio and climate control went dark. Music was still playing from the aux connection, but I could not adjust the volume at all or change inputs. Power button turned audio on and off, but the screen did not change. While this was going on, I had previously had the front defroster running, and when the screens went dark, the amber LED started blinking. Pressing "auto" would make the climate control do something, although I'm not sure exactly what mode it set itself to. Pulled into a rest area, shut the car off and took the key out for a few seconds, started it back up and everything was totally fine again.

subie bob Posted September 12, 2016 Share Posted September 12, 2016 I haven't had that happen but what I have experienced is volume randomly turning up or down and radio signal becomes nonexistent when I turn on the rear defrost Link to comment Share on other sites More sharing options...
magnusonsubie Posted September 12, 2016 Share Posted September 12, 2016 I had the exact same thing happen almost a year ago with my P-204UH from an 08 Outback in my 05. Had the volume and no other buttons work except the power button. Turned off the car, went back to it a couple hours later, restarted it and its worked since with absolutely no issues. 2005 Vader Wagon Material Tests on Ringland Failure Piston I should have held off and purchased a wagon instead of the spec.B Link to comment Share on other sites More sharing options...

Yeah, the last time it did this was probably 6-8 months ago. It's just weird, I didn't think much of it last time, although when it happened this morning as I'm driving east in traffic towards a sunrise it kinda really sucked to lose my defroster, lol.

GrasshopperLGT Posted September 13, 2016 Share Posted September 13, 2016 Mine will start to flicker. Only seen it twice. Usually once a year randomly. Link to comment Share on other sites More sharing options...

turboboost Posted September 13, 2016 Share Posted September 13, 2016 I had this issue. Check your battery and terminals. My issue was loose/weak contact due to corrosion + finding a popped fuse in my HID wiring harness. Cleaned terminals with solution and replaced all fuses (HIDs, hella horns, and aux lights) -- headunit has had no further flickering issues.

subie bob Posted September 14, 2016 Share Posted September 14, 2016 battery is getting weak I would think other issues would arise from a weak battery before the issues he's having. I took mine apart the boards show they have had some over heating and alot of dust holding the heat in the boards. They needed more efficient cooling from the beginning. I added a 3 inch fan from a computer on mine and it stays nice and cool now. Link to comment Share on other sites More sharing options...
Phate Posted September 14, 2016 Author Share Posted September 14, 2016 I had this issue. Check your battery and terminals. My issue was loose/weak contact due to corrosion + finding a popped fuse in my HID wiring harness. Cleaned terminals with solution and replaced all fuses (HIDs, hella horns, and aux lights) -- headunit has had no further flickering issues. Nothing on the car flickers at all (well, the OPT7 LED's do slightly when they are in "DRL" mode, but not when the lowbeams are actually on). Didn't even have any light dimming issues after I installed the subwoofer. Battery terminals are clean and snug, I was just in there recently installing audio nonsense. The headunit didn't flicker, it just shut down the interface completely and wouldn't turn back on until the car was off for more than 5 seconds (I attempted to turn the key off and back on quickly while driving, didn't work until I pulled over and stopped). Sound was still working at the previous volume level. I'm wondering if it is some sort of heat issue, these things do seem to run fairly warm for a car stereo.

mwiener2 Posted September 14, 2016 Share Posted September 14, 2016 Every single legacy/outback of this vintage does this at least once during it's life. Mine did it once in like 2007/8 and never did it again. Don't sweat it.

I3eXa Posted September 14, 2016 Share Posted September 14, 2016 Pretty sure that this issue is do to a loose ground connection. Mine normally flickers in the heat of the day. If I press on the plastic between the radio and the HVAC controls it flickers a lot and then goes away. There is a thread about taking the radio out and fixing it but I haven't gone that far Sent from your bedroom closet ]-.-[ Link to comment Share on other sites More sharing options...
Max Capacity Posted September 14, 2016 Share Posted September 14, 2016 Like others have said, clean the battery terminals first, make sure they are tight. This was a common issue back in the first few moths with these cars. I posted about it back in late 2004. Next, how old is the battery ? 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.

BrianEarlSpilner Posted September 15, 2016 Share Posted September 15, 2016 I had my head unit crash this year just like the others have reported. Within the week my battery died, and I had no other symptoms of a weak battery showing up. Link to comment Share on other sites More sharing options...
FJuan Posted September 15, 2016 Share Posted September 15, 2016 Every blue moon (total of 4 times in 6 yrs) my HU will freeze and the lamination would flicker. Each time I disconnected the battery to clear the ECU & HU and it came back up. It's one of those ghost in our cars. My wife's balls are delicious.

Phate Posted September 15, 2016 Author Share Posted September 15, 2016 Yeah, at this point I've pretty much chalked this one up to "It does that sometimes". My experience differes from several others in this thread in that nothing flickers at all, it just goes from "everything is working exactly as it should" to "the vents stopped blowing air and all the displays on the p-204 went dark, why can't I turn the radio down?"

Max Capacity Posted September 15, 2016 Share Posted September 15, 2016 Hey, mine would even raise or lower the radio volume sometimes. Hasn't done that in years.

Mine was doing that with a new battery that's why I decided to take it apart and clean it out and add a fan to keep it cool hasn't done it since. The radio signal is still crap when the rear defrost is on tho Link to comment Share on other sites More sharing options...
Mike07LGT Posted September 15, 2016 Share Posted September 15, 2016 Mine flickers once and awhile but never goes completely out. I bang on it and it works again. Seems like a loose connection that i dont feel like dealing with until it stops working completely 03 WRB WRX (RIP) 04 JBP STI (sold) 07 DGM Legacy GT (RIP) 12 OBP STI (DD) Link to comment Share on other sites More sharing options...
08 LGT Posted September 16, 2016 Share Posted September 16, 2016 My first LGT (RIP friend) did it a couple times a year - usually over bumps, or if you tapped the head unit with your hand, the displays would flicker. I've had the same thing happen to my "new" one over the last year once, but it seems less frequent than the first car. I've never had it totally black out, though - it's only ever happened in conjunction with vibrations/sudden bumps. Link to comment Share on other sites More sharing options...
